Protecting what we carry on our mobile phones is no longer optional: private photos, sensitive conversations, banking apps, and sensitive documents They're in our pockets every day. If you lend your smartphone to someone else, even for a moment, they might end up seeing things you'd rather keep private.
The good news is that Android offers increasingly more options to protect your privacy. From the secure folders from manufacturers like Samsung or MotorolaFrom the new private space in Android 15 to classic tricks for hiding files and apps without anyone suspecting a thing, this guide will cover everything, step by step, leaving nothing out.
Secure folders: what they are and why they are so useful
Secure folders are an isolated space within your mobile device where you can save Applications, photos, videos, and documents protected by PIN, pattern, password, or fingerprintIt's like having a mobile phone inside your mobile phone: what's inside doesn't mix with the rest of the system and only you can see it.
On Samsung, this function is called Secure folderMotorola also has a Secure Folder integrated into Moto Secure; other manufacturers offer similar solutions (app locking, private space, guest profiles, etc.), but the idea is always the same: create a private, encrypted, and concealable environment.
In addition to blocking access, many of these folders allow hide the icon itself or change the name and appearance so that it goes completely unnoticed. This way, even if someone picks up your phone, they won't even know you have a secret area set up.
Secure Folder on Samsung: Hide apps and sensitive files
On Samsung phones, Secure Folder is one of the most comprehensive tools for Hide apps and protect private filesIt works within the Samsung Knox security environment, which adds a very powerful layer of encryption and isolation.
To start using it, you need to activate it from the system settings. The usual way is to go to Settings > Security and privacy > More security settings > Secure FolderThere you can log in with your Samsung account or create a new one, and then the private folder will be generated.
Once created and unlocked, you'll see your own desktop where you can Add apps you want to hideFrom the Secure Folder home screen, tap the "+" icon and select the apps you want to move. The apps you add will appear exclusively within the Secure Folder, with their own data and settings.
Apps that move to this environment may still appear in some advanced Android settings menus (for example, in lists of installed applications), but their actual usage, notifications, and data remain limited to the Secure Folder and protected by your locking method.
Hide the Secure Folder and its icon on Samsung
With recent versions of One UI, Samsung has been refining how this space is hidden. Starting with certain versions (for example, One UI 8.0 and later), the old "Encrypt" option is renamed as “Hide Secure Folder”, and is linked to the quick shortcut icon in the notification panel.
When you tap the Secure Folder icon in Quick Settings to turn it off, the system simultaneously applies Encrypting the content and hiding the iconThis means that the Secure Folder app icon disappears from the home screen and app drawer, and the apps in the folder stop working: they can't be opened, they don't generate notifications, and they don't appear as options when sharing files.
If at any point you need to show it again in your application tray or on the desktop, you must return to Settings > Security and privacy > More security settings > Secure Folder and disable hidden or stealth mode, depending on the name used by your version of One UI. Doing so will make the icon look like any other app.
What happens if you hide system apps inside the Secure Folder?
Within the Secure Folder itself, Samsung allows you to hide some items. system applications that came pre-installedsuch as Chrome, Samsung Internet, Calendar, and others. When you do this, its icon disappears from the Secure Folder's private "desktop," but the app still appears in the folder's list of internal applications.
This leads to curious situations: for example, you can still use Chrome in the Secure Folder by opening it from the internal settings app list, but The icon is not immediately visible alongside the other private applications.If something like this has happened to you, the trick is to check the show/hide app options within the Secure Folder and re-select the app so that it reappears as a shortcut.
Secure Folder on Motorola: stealth mode and icon changes
On many recent Motorola devices, Secure Folder is managed from the app. MotoSecure or from the system's Security menu. Here, discretion is taken to a whole new level: you not only block apps and files, but you can also Change the app icon and name so that no one suspects anything.
To change this appearance, first open the Secure Folder and unlock it. Then, from the menu, access the hidden icons options (or "hidden icons," depending on the translation) and enable the corresponding function. There you can choose an alternative icon and a different nameso that Secure Folder can look like, for example, a harmless notes or calculator app. If you'd like, you can see how. Organize your apps with smart folders to distribute access points and make the concealment more natural.
If you later want to revert to the original appearance, you'll have to go back to Moto Secure or Settings > Security and privacy > Enhanced security and privacy > Secure FolderTo disable hidden icons, go into the hidden icons settings and turn the option off. Doing so will restore the app's default icon and name.
Stealth mode: Make the Secure Folder disappear
In addition to disguising the icon, Motorola includes a covert mode This directly causes the Secure Folder to disappear from the app tray or home screen (on models without an app drawer). In other words, there will be no visual trace of its existence.
To activate it, go to Secure Folder, unlock it, and from the menu, select the option corresponding to Stealth Mode. As soon as it's activated, The Secure Folder shortcut is no longer visibleTo regain access, you will need to do so from Moto Secure or from the device's advanced security settings.
When you want it to revert to its normal app appearance, go to Moto Secure > Secure Folder > Stealth Mode and disable hidden mode. From then on, you'll see it again on the home screen or in the app drawer.
Change the Secure Folder lock on Motorola
The lock type for this private space can also be modified to suit your security level. You can use pattern, PIN or password, with the possibility of adding biometrics if the model allows it.
To do this, open the Secure Folder, unlock it, and go to the settings menu. From there, look for the option Change lock mode or “Authentication settings.” The system will ask you to unlock the folder again, and then you can choose between:
- Boss: You draw a figure on a grid.
- PIN: 4 to 16 digit numeric code (the longer, the better).
- Password: combination of letters, numbers and symbols, also from 4 to 16 characters.
It is recommended to use a long and unpredictable codeespecially if you are going to store very sensitive documents or images.
Private space in Android 15: a “parallel mobile” inside yours
Android 15 brings a very interesting built-in feature: private spaceIt's not exactly just another secure folder, but a parallel environment where you can install applications separate from the rest of the system, with its own Google account and credentials.
The idea is that you can use this space in two main ways. On the one hand, so that apps with sensitive information (banking, investments, sensitive email, work files, etc.) require extra verification to open. On the other hand, for hide apps that you don't want to see in the regular drawer or usage history, so that they can only be accessed by entering this private environment.
The private space functions like a second "hard drive" inside the mobile phone: to manage it, it's best to use a advanced file manager. The apps don't move, they are installed separatelyIf you have an app on the main system and want it in your private space as well, you'll need to reinstall it there. Then you can decide whether to keep both copies or uninstall the public version, leaving only the private version.
How to configure the private space
To create your private space on Android 15, go into your phone's settings and then to Security and privacyInside, look for the Privacy section and click on the option Private spaceThe system will show you an explanation of how it works and give you the option to start configuring it.
When you click on Configure, you will need to associate a google account to your private space. It can be the same account you use on the rest of your phone or a completely different one. This allows you, for example, to separate your work apps from your personal apps with different accounts.
During the process, you will see several key settings:
- Blocking private spaceYou can use the same screen unlock method or define a unique PIN/password for this environment, also adding your fingerprint if you want speed without losing security.
- Automatic blockingYou choose when the space is locked again. Only on restart, every time the screen is locked, or after a few minutes of inactivity (for example, 5 minutes).
- Show or hide private spaceIf it's visible, its shortcut appears at the bottom of the app drawer. If you hide it, it disappears from view, and you'll have to use the Android search function to find it.
- Elimination of spaceFrom here you can completely delete the entire private environment if you no longer need it.
Install apps within the private space
Once configured, there are two main ways to Add applications to this spaceIf the space is visible in the app drawer, enter it and press the Install button: the app store associated with the Google account chosen for the space will open, and you can download whatever you want directly from there.
The other way is to "duplicate" an app you already have. To do this, press and hold the app icon in the regular app drawer and select the option Download privately (or the equivalent label shown by your manufacturer). The system will install that same app within the private space.
Once you have the app there, you can decide whether to leave it visible in the main app drawer as well, or if you prefer Keep only the private copy and uninstall the public oneThus, for all practical purposes, the app will not exist for anyone who checks your phone.
Hide apps on Android using built-in settings
Beyond secure folders and private spaces, many Android phones include launcher settings to hide apps No additional installation is required. The exact location varies depending on the customization layer, but the pattern is usually similar.
In many cases, simply open Settings and search for “Hide apps” or “Hide apps on the home screen and app screens.” If the option appears, you can tap it and Select the applications you don't want to be displayedAn internal "Hidden Apps" section is usually created where you can review what you have hidden.
If the setting doesn't appear in the search, try going to Settings > Home screen Scroll down to find a section for hidden apps. From there, select the apps you want to hide and confirm the changes. These apps will disappear from the home screen and app drawer, although they will still be installed.
This method is useful for apps that are not extremely sensitive (games, social networks, tools you don't want others to use), but it doesn't replace a secure folder: anyone who knows Android well could still locate them from the menus of installed applications if they search hard enough.
Use specialized apps to hide apps and files
If your phone doesn't have advanced hiding features, you can always resort to third-party apps specifically designed to hide contentMany of them are disguised as calculators or other basic utilities, so they go completely unnoticed.
Among the most common on Google Play are "fake" calculators like HideU: Calculator Lock, Calculator Vault: App Hider, or Calculator – Hide apps, photos. They all share the same idea: The app looks like a normal calculator, but entering a specific PIN reveals a hidden space. where to store other applications, photos, videos, and files.
In addition, there are more traditional file management utilities such as File Hide Expertwhich focuses on hiding folders and documents rather than disguising apps, and blockers like AppLock or gallery-oriented solutions, such as Gallery lock or KeepSafe, which allows you to put a PIN on photos and videos.
Examples of useful apps for protecting content
- File Hide ExpertThis feature lets you choose folders, photos, videos, and other files to hide or show with a single tap. It works the same as folder renaming tricks, but visually, without having to create special files or deal with complicated paths.
- AppLockIdeal if you want to block access to specific apps (gallery, messaging, settings, etc.) with a PIN, pattern, or password. This way, even if someone has your phone, they won't be able to open certain apps without your code.
- Gallery lockIt focuses on hiding photos and videos. It requires a password to view the hidden content and, in many cases, can even Take a picture of anyone trying to log in with an incorrect password.However, be careful: if you uninstall the app without having displayed the photos first, you could lose access until you reinstall it.
- KeepsafeIt acts as a safe for photos and videos, organized into folders. You can protect collections with a PIN. The free version offers the basics for hiding images, and the paid version adds extra features.
Hide apps with a guest account or private mode
Many Android devices include a Guest mode or user profilesIt's a very effective way to lend your phone without revealing your entire life, because it completely separates your apps, data, and settings from the space the other person will use.
On some Samsung devices, for example, you can activate a guest profile from Settings > Accounts and Backup > Users > GuestThere is also usually the option to add a new permanent user, which is useful if someone uses your phone frequently but you want them to have their own separate space.
When you switch to guest mode, it shows only a limited set of appswithout access to your personal accounts or private data. To the guest, the other applications don't even exist, making it a very clean way to "hide" content without having to move anything.
Disable apps so they don't appear or bother you.
In cases where you cannot uninstall a system app (for example, manufacturer bloatware), there is another option: disable itThis hides the icon from the home screen and prevents the app from running in the background, thus also saving resources and data.
To do this from the home screen, simply find the application icon, press and hold it, and choose the option. Deactivate or "Disable" in the pop-up menu. This will disable the app and remove it from the app drawer.
If you prefer to do it from the settings, go to Settings> ApplicationsSelect the app in question and tap Deactivate. The application will stop working and will be hidden, although it will still appear in the system's internal app list, since it hasn't been completely uninstalled.
It's a very practical method for Clean your phone of apps you don't use And you don't want anyone to open it by mistake, although it's not the ideal solution for hiding really sensitive content.
How other Android manufacturers hide apps and files
Each brand adds its own tricks to reinforce privacy. While a Samsung-style secure folder isn't always available, they usually do exist. application blocking or hiding functions which could be perfect for you.
On Xiaomi: App locking and hidden apps
Xiaomi offers several ways to control access to your apps. The first is... Application blocking, accessible from Settings > Applications > App lockWhen you activate it, you set a passcode and select which apps you want to block.
It is true that, in this case, the apps do not disappear completely from the home screen, but Every time someone tries to open them, they will have to enter the code.It's a good defense for content that you don't mind being seen in the drawer, but that you don't want anyone to be able to open without permission.
Additionally, you can use the app on newer Xiaomi models Security of the system. Within, scroll down to the "Hide apps" option and select the ones you want. From that moment on, they will be hidden, and to find them you will have to return to that same Security section.
Live: App Privacy and Encryption
On Vivo phones, the settings are located in the Security menu. Within it, there is a section for Application privacy and encryption which allows you to set a privacy password and security questions.
Once configured, you will find the option to Hide appsThere you choose which apps you want to hide. When you need to access them, you'll have to go back to App Privacy and Encryption and enter "View hidden apps". In practical terms, it's very similar to having a secure folder for apps.
On Oppo: hidden apps with code from the dialer
Oppo proposes a rather ingenious system. From Settings > Security and privacy > Hide apps You can select an application to hide. The system will ask you to define a privacy password and a special access code for hidden apps.
Once configured, those apps will no longer appear on your home screen. To open them, you won't have a visible icon: you'll have to Enter the access code on the numeric keypad. (as if you were going to dial a phone number). Doing so will display the list of hidden, protected applications.
OnePlus: Built-in privacy and passcode access
On OnePlus you can go to Settings> Privacy and go to the Privacy tab, where you will find the section Hide appsWhen you activate it, the system will ask you to set up a password and a security question.
Then you can select the apps you want to hide. These apps will be hidden from the home screen and won't appear in the recent apps list. However, an advanced user might be able to see them in some internal settings, just like with other Android skins.
To see your hidden apps, just like on Oppo, you can use an access code on the numeric keypadOnce the correct code is entered, the list of hidden applications will be revealed so you can open them normally.
Hide folders and files with system tricks
If what worries you isn't so much the apps as photos, videos or documentsAndroid has a very useful behavior: by default, it ignores folders and files whose name begins with a period or that contain a special file called ".nomedia". Taking advantage of this is a very effective way to hide content from regular apps.
To use these methods you will need a File BrowserMany mobile phones come with one as standard, but apps like "ES File Explorer" or other similar (free and complete) managers allow you to browse all the folders on the device without problems.
Create a hidden folder with a dot in front.
Open your file explorer and navigate to the location where you want to save the private content. Create a new folder and give it a name that begins with a period, for example. .photos (without quotation marks). That initial point tells the system to treat it as hidden.
Anything you move to that folder will no longer appear in apps that scan storage, such as the photo gallery or some media players. In practical terms, The images or videos "disappear" from all normal appsHowever, they still exist and you can see them from the explorer if you activate the option to show hidden files.
Use the .nomedia file to hide specific photos and videos
If you don't want to hide an entire folder, but only prevent certain photos and videos from appearing in the galleryYou can use the file trick .nomediaThe procedure is simple: place the images or videos you want to hide inside a normal folder (without a period in front) and, inside that folder, create an empty file called “.nomedia” (without an extension).
When the apps see that file, They will stop indexing the multimedia items in that folderThe gallery and other programs will stop displaying photos and videos, although they will still be accessible from the file explorer. For more step-by-step details, see how Hide photos on AndroidHowever, make sure your browser has enabled the display of hidden folders and filesOtherwise, you could lose track of your own content and think it has disappeared, when in reality it is still perfectly fine.
How to find hidden apps on Android
You might want to check what you have hidden (or suspect that your own phone has something hidden that you don't remember). The way to find those apps depends a lot on... how and with what they were hidden.
If you've used a third-party app (especially those disguised as calculators), you'll likely have to Open that fake calculator and enter a PIN or password. to view the hidden content. Without that code, it will appear to be a normal, harmless app.
If you used a built-in system or manufacturer feature, first review the sections on Security, Privacy, or Applications In the settings. There's usually a "Hidden apps" section or something similar where they're listed. On phones like Oppo or OnePlus, remember that you might need to enter a code on the dial pad for them to appear.
Since you're here, it's a good time to Clean your Android of apps you don't use. or suspicious programs that might be spying on your activity. Uninstalling or disabling what you don't need not only improves privacy, but also frees up storage and improves performance.
With all these tools—secure folders, private space, guest mode, app blocking and disabling, tricks with hidden folders, and specialized apps—you have a huge range of options to Your mobile phone will only show what you want to show.By combining several of these measures, you can lend your phone with peace of mind, store sensitive documents without fear, and ensure that your most sensitive apps remain out of reach of both curious onlookers and more dangerous eyes on the Internet.
